NITED STATES WILLIAM HIPPERLING, OF

PATENT OFFICE.

SHEET-METAL CAN.

SPECIFICATION forming part of Letters Patent No. 333,945, dated January 5, 1886.

Application filed November 30, 1885. Serial No. 184,269. No model.)

To all whom it may concern:

Be it known that I, WILLIAM HIPPERLING, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Sheet-Metal Cans,

of which the following is a specification.

The invention relates to improvements in sheet-metal cans; and it consists in a novel formation of the crimp by which one or both of the heads are secured to the body of the can, the purpose being to so unite the head and body that the two can only with difficulty be separated, and that the joint between them [5 will be substantially liquid-tight, although no solder need beemployed.

The invention will be fully understood from the description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a can em-' ploying the invention. Fig. 2 is a central vertical section of a portion of same. Fig. 3 is a central vertical section of the head and body of the can, showing their construction and relation to each other prior to the crimp being formed; and Fig. 4. is a central vertical section illustrating the form of the crimp preferred for large cans.

In the drawings, A designates the body of the can; B,the head thereof, and G the crimp uniting the head to the body.

In carrying the invention into effect, the head and body are first formed and arranged in relation to each other as shown in Fig. 3-

that is, the body is made with the plain perpendicular edges 66 and the head B, with an annular depression, b, encompassed by a vertical flanged, and a horizontal flange,e.

In the assembling of the parts the vertical flange (1 passes downward against the inner surfaces of the perpendicular edge a, and the horizontal flange 6 extends outward over and beyond said edge, as shown in Fig. 3. After 5 the parts have been arranged as stated above,

by asingle operation of the apparatus the outer edges of the flange e are turned over the edges a, the latter deflected outward a distance about equal to one thickness of the sheet metal, and

an annular depressed shoulder, f, formed in the flange d, the latter entering and' conforming to a like depression in the edge a, and the extreme outer edges of the flange e terminating at the base of the outwardly deflected edge a. The lower edges of the flange d closely encompass the lower portion of the deflected edge a, and are on about the same horizontal plane with the extreme edges of the flange e. The crimp, formed as above described, is effective in that the head can not be separated from the body without a vigorous effort to accomplish that purpose, and will not be disturbed by the knocks and jars to which the can would be subjected in ordinary use.

WVhen the crimp above described is to be applied to large cans, the annular shoulder f will be a little more pronounced than that shown in Fig. 2, and a more fully developed shoulder, m, will be formed in the edge a, as shown in Fig. 4, the extreme edges of the 7c flange 6 being caught under the shoulder m, as indicated,

The apparatus described in Letters Patent issued to me July 17, 1883, and numbered 281,508, may be made use of in forming the 7 crlmp.

What I claim as my invention, and desire to secure by Letters Patent, is

An improved crimp for sheet-metal cans having a body and head, which consists of the flanges d and e on the head and the outwardlydeflected edge a on the body, the flange d having an annular shoulder,f,and the extreme edges of the flange e terminating at the base of the deflected edge a, substantially as shown and described.

Signed at New York, in the county of New York, and State of New York, this 23d day of November, A. D. 1885.

WILLIAM HIPPERLING.
